Got a few questions for clarification. Are there slaves? Is there a conquored race? What's the skin color of ppl, and does it change based on the regions?

Northerners are Inuits. Southerners are Mexican or white. East-Heartland-West are Anglo-Americans. There are no slaves, just servants, and Hands in the South. The only race who got conquered would be the Wyrmlings, and they work for Dragons. Wyrmlings are white too.

Are there trains or other advanced vehicles? It seems the tree sap could be used to generate steam power.

They definitely could be used to generate steam power. And while there is probably the design somewhere in the Imperial Boffin Corps HQ (I need to update the codex for these guys) it hasn't happened yet. Beyond the World, of course, it's fair game.

Also, I like the way mages are used here. Very nice use of magic.

Thanks! I spent a really long time figuring out how to have magic be present, yet not dominate the World.
